* Also check __i586__/__i686__ for HAS_I586/HAS_I686H.J. Lu2015-08-192-8/+15

* Fix -Wundef warnings in elf/tst-execstack.c.Joseph Myers2015-08-192-0/+4
| | | | | | | | | | | | | | | | | | | | | | To remove -Wno-error=undef, we need to fix the remaining cases where there are -Wundef warnings in the testsuite. One of those places is in elf/tst-execstack.c. tst-execstack.c tests USE_PTHREADS with #if. nptl/tst-execstack.c defines USE_PTHREADS to 1 before including ../elf/tst-execstack.c, while elf/tst-execstack.c, when compiled directly, leaves it undefined. This patch adds a setting of CPPFLAGS-tst-execstack.c to elf/Makefile. An alternative approach would be to rename tst-execstack.c to tst-execstack-main.c and have two different tst-execstack.c files include it, each with an appropriate USE_PTHREADS #define. Tested for x86_64. * elf/Makefile [$(have-z-execstack) = yes] (CPPFLAGS-tst-execstack.c): New variable.
* Fix -Wundef warnings in login/tst-utmp.c.Joseph Myers2015-08-192-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To remove -Wno-error=undef, we need to fix the remaining cases where there are -Wundef warnings in the testsuite. One of those places is in login/tst-utmp.c. When included from tst-utmpx.c, <utmpx.h> is included instead of <utmp.h>, meaning the _HAVE_UT_* macros are not defined. The test is prepared for them not being defined, in that all the relevant conditionals also include "defined UTMPX". However, they test the _HAVE_UT_* macros first, so resulting in -Wundef warnings. This patch does the minimal fix of swapping the || operands. This is logically correct - avoiding checking a macro we know will not be defined in the case where it is not defined. It won't fix such warnings for the case where the toplevel bits/utmp.h is used and most _HAVE_UT_* aren't defined at all even when <utmp.h> is included, but that case doesn't apply to any current glibc configuration. Fixing it would also be tricky in that, while glibc itself consistently uses _HAVE_UT_* in ways that would work with 0 instead of undefined, external packages that use the macros expect defined / undefined instead of 1 / 0 (codesearch.debian.net shows uses by util-linux, python-utmp, libsys-utmp-perl). Tested for x86_64. * login/tst-utmp.c [_HAVE_UT_TYPE || defined UTMPX]: Change conditional to [defined UTMPX || _HAVE_UT_TYPE]. [_HAVE_UT_TV || defined UTMPX]: Change conditional to [defined UTMPX || _HAVE_UT_TV]. [_HAVE_UT_TV - 0 || defined UTMPX]: Change conditional to [defined UTMPX || _HAVE_UT_TV - 0].
* Fix MIPS -Wundef warnings for __mips_isa_rev.Joseph Myers2015-08-183-3/+9
| | | | | | | | | | | | | This patch fixes -Wundef warnings relating to __mips_isa_rev being undefined. Tested for mips64 (all three ABIs) that there is a clean build and testsuite run with -Wno-error=undef removed (and my other -Wundef patches applied). * sysdeps/mips/dl-machine.h [__mips_isa_rev < 6]: Change conditionals to [!defined __mips_isa_rev || __mips_isa_rev < 6]. * sysdeps/mips/machine-gmon.h [__mips_isa_rev < 6]: Likewise.

* Fix lang_lib/lang_term as per ISO 639-2 [BZ #16973]Marko Myllynen2015-08-1811-15/+41
| | | | | | | | | | lang_lib (which reflects ISO 639-2/B (bibliographic) codes) and lang_term (which reflects ISO 639-2/T (terminology) codes) should be identical except for those languages for which ISO 639-2 specifies separate bibliographic/terminology values. I used this Library of Congress page as the source: http://www.loc.gov/standards/iso639-2/php/code_list.php
* regexp.h: update Versions to match file usage [BZ #18681]Zack Weinberg2015-08-182-0/+7

* hppa: sigaction.h: update define export based on __USE_XOPEN2K8Mike Frysinger2015-08-182-0/+7
| | | | | This brings hppa in line with other ports by exporting a few more defines based on the __USE_XOPEN2K8 define and not just __USE_MISC.

* hppa: assume TLS everywhereMike Frysinger2015-08-186-111/+10
| | | | | | | This brings hppa inline with all the other arches and main code where we require TLS support everywhere. That means dropping the defines USE_TLS and USE___THREAD, and dropping the binutils check (since we already have a version requirement that is new enough).
* Fix csqrt spurious underflows (bug 18823).Joseph Myers2015-08-177-10/+1861
| | | | | | | | | | | | | | | | | | The csqrt functions scale up small arguments to avoid underflows when calling hypot functions. However, even when hypot does not underflow, a subsequent calculation of 0.5 * hypot can underflow. This patch duly increases the threshold and scale factor to avoid such underflows as well. Tested for x86_64, x86 and mips64. [BZ #18823] * math/s_csqrt.c (__csqrt): Increase threshold and scale factor for scaling up small arguments. * math/s_csqrtf.c (__csqrtf): Likewise. * math/s_csqrtl.c (__csqrtl): Likewise. * math/auto-libm-test-in: Add more tests of csqrt. * math/auto-libm-test-out: Regenerated.

* stpncpy: fix size checking [BZ #18975]Zack Weinberg2015-08-144-13/+172
| | | | | | | | | | I think the last clause of the conditional, || __n <= __bos (__dest) may be backward. The code should call the runtime-checking function if __n is not constant, or if __n is known to be LARGER than the size of the destination.
* Fix fma spurious underflows (bug 18824).Joseph Myers2015-08-147-4/+288
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various fma implementations have logic that, when computing fma (x, y, z) where z is large (so care needs taking to avoid internal overflow) but x * y is small, scale x * y up instead of down to avoid internal underflows resulting from scaling down. (In these cases, x * y is small enough that only its sign actually matters rather than the exact value.) The threshold for scaling up instead of down was correct for "if the unscaled values were multiplied, the low part of the multiplication could underflow", and the scaling was sufficient to ensure that the low part of the multiplication did not underflow (given that cases of very small x * y - less than half the least subnormal - were previously dealt with). However, the choice in the functions wasn't between scaling up or no scaling, but between scaling up and scaling down (scaling down actually being needed when x * y isn't so small compared to z and so the exact value does matter). Thus a larger threshold is needed to ensure that scaling down doesn't produce values the multiplication of whose low parts underflows. This patch increases the thresholds accordingly. Tested for x86_64, x86 and mips64 (with the MIPS version of s_fmal.c removed so that the ldbl-128 version gets tested instead of the soft-fp one). [BZ #18824] * sysdeps/ieee754/dbl-64/s_fma.c (__fma): Increase threshold for scaling x * y up instead of down. * sysdeps/ieee754/ldbl-128/s_fmal.c (__fmal): Likewise. * sysdeps/ieee754/ldbl-96/s_fmal.c (__fmal): Likewise. * math/auto-libm-test-in: Add more tests of fma. * math/auto-libm-test-out: Regenerated.

* Remove incorrect register mov in floorf/nearbyint on x86_64Siddhesh Poyarekar2015-08-143-2/+7
| | | | | | | | | | | | | The change in 0b5395f052ee09cd7e3d219af4e805c38058afb5 replaced calls to __get_cpu_features@plt followed by a mov from rax to rdx, with a single macro LOAD_RTLD_GLOBAL_RO_RDX. It is pretty clear that there was a typo in s_floorf and __nearbyint due to which the (now incorrect) mov was not removed. This patch removes that mov. * sysdeps/x86_64/fpu/multiarch/s_floorf.S (__floorf): Remove unnecessary movq. * sysdeps/x86_64/fpu/multiarch/s_nearbyint.S (__nearbyint): Likewise.
* Add more random libm-test inputs.Joseph Myers2015-08-135-105/+2347
| | | | | | | | | | | | | | | | This patch adds more test inputs to various libm functions found through random generation to have larger ulps errors than previously listed in libm-test-ulp, on at least one of x86_64 and x86. Tested for x86_64 and x86. * math/auto-libm-test-in: Add more tests of acos, acosh, asin, asinh, atan, atan2, atanh, cabs, cbrt, cosh, csqrt, erf, erfc, exp, exp2, lgamma, log, log1p, log2, pow, sin, sincos, tan, tanh and tgamma. * math/auto-libm-test-out: Regenerated. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
* Fix tanh missing underflows (bug 16520).Joseph Myers2015-08-1310-4/+390
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to various other bugs in this area, some tanh implementations do not raise the underflow exception for subnormal arguments, when the result is tiny and inexact. This patch forces the exception in a similar way to previous fixes. Tested for x86_64, x86, mips64 and powerpc. [BZ #16520] * sysdeps/ieee754/dbl-64/s_tanh.c: Include <float.h>.
